"There is every indication the Sport Turismo will come but we will have to wait until next year to know for sure." Porsche Australia's head of public relations told CarAdvice.

With the new Panamera sedan set for arrival in February next year, the wagon will bring about the practicality of five seats while offering more storage capacity, marking the first time the German sportscar maker has offered such a car.

The four-seat only design of the sedan has been a sore point in some markets for Porsche, making the Sport Turismo an attractive offering.

It’s unclear what engine offerings will be available with the wagon, however we suspect the 2.9-litre V6 and 4.0-litre diesel are guaranteed, with the top-spec Turbo variant also a likely candidate.

The wagon may also be used to showcase new variants of the Panamera range, with GTS, Turbo S and hybrid options still to make their debut.

The Panamera's diverse underpinnings allow for numerous variations of the model. The new luxury sedan and wagon is built up the 'MSB' platform, which the Volkswagen Group is expected to use across other models, including the next generation Bentley Continental GT.
